Vintage spring bracelet

Vintage see pictures. Looks great on but the gold is a bit worn. You don’t see the wear when it is on. Gorgeous trendy. I just noticed a bit of rust where the spring is. WD40 should remove it. I wear 7 to 7 1/2” bracelet. Bracelet operates smoothly but it is vintage and wear is consistent with the age. #7 Boutique Box
